LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 636,207, dated October31, 1899.

Application filed January 3, 1899.

To a/ZZ whom t may concer/'n.-

Be it known that 1, JOHN LUTHER KINNEY, a citizen of the United States,residing at Burlington, in the county of Alamance and State of NorthCarolina, have invented a new and useful Loom-Shuttle, of whichthe'following is a specification.

My invention relates to loom-shuttles, and has for its object to providea simple and improved construction f tongue and quill or bobbin, andparticularly to provide an improved construction of means'for lockingthe quill or bobbin upon the tongue, the opera# tion of the lockingdevice being automatic and the same being positively held in itsengaging position when the tongue is operatively located in the cavityof the shuttle shell or body.

Further objects and advantages of this invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claims. v

In the drawings, Figure 1 is a longitudinal section of a shuttleconstructed in accordance with my invention, the parts being shown intheir normal or operative positions. Fig. 2 is a similar view showingthe bobbin-tongue elevated to release the bobbin. Fig. 3 is a detailview in perspective of portions of the bobbin-tongue and bobbin, thelatter being shown displaced or partly removed from the tongue. Fig. 4is an inverted plan view of the same, showing the parts in theirinterlocked or engaged positions.

Similar reference characters indicate corresponding parts in all thefigures of the drawlngs.

l designates the shuttle shell or body, in the recess or cavity of whichis mounted a tongue 2, adapted for swinging movement into and out ofsaid cavity or recess upon a transverse pivot-pin 3. The tongue isenlarged or increased in thickness toward its pivoted end, as shown at4, and terminates in a still further enlarged shoe 5, which, in commonwith the adjacent thickened portion of the tongue, is bifurcated to forma longitudinal vslot 6. In this slot is mounted a latch 7 upon the pivot3, which supports the tongue, and carried by the latch is a locking-Serial No. 701,016. (No model.)

pin 8, adapted to be sheathed within the slot when the latch is in oneposition and to be extended beyond the side surface of the tongue whenthe latch is in another position. Located in the slot is a fixed block9, of which the sides form stops for limiting the swinging movement ofthe latch in opposite directions.

The shoe of the tongue is provided with a transverse shoulder 10 and acam-faced or oblique surface 11, and arranged in operative relationtherewith is a spring-pressed follower l2, which is( adapted to bearpermanently against the rear surface of the shoe in contact with saidoblique or cam face to secure the tongue yieldingly in one of itsadjusted positions. Said follower is actuated by a spring 13, andconsists of a disk having a fiat face for contact with the shoe of thetongue and a stem 14 to extend rearward into the spring, and the springand follower are mounted in a guide 15, formed in the shuttle shell orbody in communication with the main cavity or recess thereof. When thetongue is in its normal position within the cavity of the shuttle, thefollower bears against the camface, while the transverse portion orshell 10 of the shoe, which is located below said camface,bearsagainstas'top-shoulder 10, formed on the shuttle shell or body, and whenthe free end of the tongue is elevated to swing the saine out of thecavity or recess the oblique or cam face of the shoe traverses thefollower, thereby repressing the same in opposition to the tension ofits actuating-spring until the toe or point of the shoe bears againstthe follower.

Registering transversely With the transverse shoulder or shell portionof the shoe is a heel portion 16 of the latch, and hence when the tongueis in its normal position said heel portion of the latch bears againstthe stopshoulder of the shuttle-shell simultaneously with that of theshoe.b Thus the free end of the latch is elevated to extend thelockingpin to engage an opening 17 passing centrally through the quillor bobbin 18, which is fitted upon the tongue. In the same way as thefollower traverses the cam or oblique face toward the toe of the shoethe heel of the latch is released, and pressure is applied to the toeportion 19 of the latch to reverse the IOO latter and thus withdraw thelocking-pin into the longitudinal slot of the tongue. Thus it will beseen that the follower and actuating-spring are adapted to secure thetongue in either of its adjusted positionsnamely, either within thecavity of the shuttle-shell or projecting obliquely7 therefromand thatthe pivotal latch, which is mounted coaxially with the tongue, is alsoadapted for actuation by the same follower, whereby when the tongue isarranged within the shuttle-shell the locking-pin is extended to engagethe socket in the quill or bobbin, and is thus held positively as longas the tongue maintains its operative position, and when the tongue isdeiected to provide for the removal of the quill or bobbin from thetongue the locking-pin is withdrawn from the socket to release thequill.

Furthermore, I preferably extend the stopblock 9 to form a rib 20 forengagement with one of a plurality of notches 2l, formed in the rear endof the quill or bobbin at diametrically opposite points. I preferablyemploy two of these notches for engagement with the rib of thetongue-slice to facilitate the engagement ofthe bobbin, andcorrespondingly I provide the latter with a plurality of sockets .forengagement with the locking-pin of the latch.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

Having described my invention, what I claim isl. The combination with ashuttle-body, of a slotted tongue pivoted therein, a latch in the slotof the tongue pivoted coaxially with the tongue, said latch having alocking-pin adapted to lie in the slot of the tongue to permit thepassage of a quill onto the tongue and to project from the slot to enteran opening in said quill to prevent its removal from the tongue, ashoulder 4upon the tongue adapted for engagement by the quill to stopthe latter in operative alinemeut with the latch longitudinally, a ribupon the tongue adapted to enter a slot in the quill and hold the latterin operative alinemeut with the latch transversely, and aspring-actuated follower engaging the latch and adapted to hold it atthe limits of its motion.

2. The combination with a shuttle-body, of 55 a slotted tongue pivotedtherein, a latch in the slotted tongue pivoted coaxially with thetongue, said latch having a locking-pin adapted to lie in the slot ofthe tongue to permit the passage of a quill onto the tongue and toproject from the slot to enter an opening in said quill to prevent itsremoval from the tongue, a spring-actuated follower engaging the latchand adapted to hold it at the limits of its motion, and a fixed rib onthe tongue adapted to engage a notch in said quill to prevent rotationof the latter.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
